NIM reference design for CATV set-top boxes & home gateway subsystems

ANADIGICS launched a cable television NIM (Network Interface Module) reference design which incorporates its AIT1042 integrated RF tuner and the ST0297E QAM demodulator with A/D Converter from STMicroelectronics. The reference design offers tuner-demodulator subsystem that eliminates complicated RF front-end design issues.
Jointly developed by ANADIGICS and ST Microelectronics, the design provides solution that reduces the footprint, cost and development time required to bring new cable TV set-top boxes and home gateway products to market.

Some of the features and advantages of this reference design are:

1. The full-NIM reference design offer an optimized hardware-and-software solution that allows cable products to be quickly field tested, qualified, and brought to mass production.
2. The platform comes with full design support, including circuit schematics, printed circuit board layout, bill of materials and core software.
3. Set-top box manufacturers can build upon the design or customize it to meet their specific requirements, applying the reference design directly to their main PCB for a "tuner-on-board" solution.
4. Manufacturers of canned tuners can use the higher levels of integration offered by this design to reduce the number of discrete components in a full-NIM tuner/demod solution.
5. The reference design meets the requirements of cable operators in Japan, China, Europe, and other regions employing ITU-T J.83 Annex A/C and DVB-C bit streams.
6. ANADIGICS' AIT1042 is developed for use in CATV and HDTV tuners, set-top boxes and PC TV tuner cards.
7. This new RF tuner device includes an up-converter with RF gain control, a down-converter, a digital IF amplifier with gain control, a dual PLL synthesizer, and a VCO with integrated tank circuits,

Package: 7mm x 7mm x 1mm surface mount package.
